IMPROVEMENT IN BOOK-RESTS.

Specification forming part of Letters Patent No. 139, 341, dated May 27,1873; application filed May 19, 1873.

To all whom it may concern Be it known that I, LIDA TARRING, of the cityof Washington, District of Columbia,

have invented certain Improvements in Book- Rests, of which thefollowing is a specification:

Nature and Object of the Invention.

Description of Drawings. Figure 1 is a side elevation of a desk with theiblding-rest attached. Fig. 2 is a side elevation of a desk,` showing amodification of the device as applied to a desk for two persons. Fig. 3is a front elevation of a desk, showing one desk with hinges and oneWithout.

General Description. Similar reference-letters denote similar A is thedesk, to the sides of which are attached, with suitable thumb-screws b,arms a. These arms may be curved orstraight, and, if necessary, providedwith a `middle hinge to facilitate folding. They have also slots throughwhich pass thumb-screws c, which are intended to clamp and hold at anydesired angle the rest B. The third point of support for the rest isfound on the top of the desk. The rest may be furnished'with hinges atthe line which divides it in halves horizontally, as shown in Fig. 2.These are for the of the parts of the rest bearing upon the desk toprevent scratching of the finished work.

The slots in the arms a a are to provide for the proper adjustment ofthe rest at the desired angle. y Y L In Fig. l I show a modification ofmy invention. In this I secure the slotted arm a to the top instead ofthe sides of the desk. I propose also to divide Bthe rest into two partsvertically so as to apply it to a desk for two or more persons, so thatone part may be in use while the other is out of the way.

When heavy weights are to be supported on the rest it may be foundnecessary to fasten the rest and slotted Yarm together by a hook or rod,which may be countersunk in the Wood of the rest and hinged to the same.
